In vacuum conditions,micron-grade ZrC ceramic particles with 1.1% volume fraction were added into low-carbon microalloyed steel.The steel was hot-rolled in Φ450 mm experimental hot mill.The steel grains were refined to 5.5 μm after hot rolling.The tensile strength and yield strength of the hot rolled steel were 635 MPa and 517.5 MPa respectively,and its HV hardness(HV5) was 214.ZrC particles can strengthen the steel obviously,and can also refine the grains of the steel in the course of crystallizing and solidifying of the steel and during hot-rolling process afterwards.The microstructure of the hot rolled steel is ferrite.Inclusions are dispersed in the steel.
